1.One of the effects of global warming is the destruction of many important ecosystems.Changing and erratic climate conditions will put our ecosystems to the test, the increase in carbon dioxide will increase the problem. The evidence is clear that global warming and climate change affects physical and biological systems. There will be effects to land, water, and life. Already today, scientists are seeing the effects of global warming on coral reefs, many have been bleached and have died. This is due to warmer ocean waters, and to the fact that some species of plants and animals are simply migrating to better suited geographical regions where water temperatures are more suitable. Melting ice sheets are also making some animals migrate to better regions. This effects the ecosystems in which these plants and animals live. Several climate models have been made and they predict more floods (big floods), drought, wildfires, ocean acidification, and the eventual collapse of many ecosystems throughout the world both on land and at sea. There have been forecasts of things like famine, war, and social unrest, in our days ahead. These are the types of effects global warming could have on our planet.

2.Another important effect that global warming will bring is the loss and endangerment of many species. Did you know that 30 percent of all plant and animal species alive in the world today are at risk of extinction by the year 2050 if average temperatures rise more than 2 to 11.5 degrees Fahrenheit. These mass extinctions will be due to a loss of habitat through desertification, deforestation, and ocean warming. Many plants and animals will also be affected by the inability to adapt to our climate warming.

Some species will survive though because they will migrate to other parts of the world where they can survive. A good example of that happening is the red fox that has already done it. The red fox used to live mainly in North America, but has migrated now to the Arctic. People like you and me are also in danger, people living in coastal areas will be badly hit if sea levels rise. Desertification will also be a problem for humans, food may become scarce.

3.One very disappointing effect of global warming is war and conflicts.With a decline in the amounts of quality food, water, and land, it could bring an increase in global security threats, and war. Take the country Sudan for example, in that region global warming has played an important role. There is conflict in Sudan, global warming is not the only cause, but it has played its part. The roots of the problem in Sudan can be traced back to climate change, and the scarcity of natural resources. The conflict in Sudan started during a time of intense drought. Scientists and military analysts are predicting that climate change and the devastation it causes could bring war and conflict. When sufficient amounts of water and food are running short that is when war can come about. What this brings to light is the fact that ecological crisis and violence are both linked.

4.Economic calamities are another effect that global warming could bring. Take hurricane Katrina for example, one thing that climate change does is that it brings us more extreme storms like Katrina. Hurricane Katrina resulted in millions and millions of dollars in damage. When severe storms and floods occur, crops, homes, businesses, and more all fail, and that costs a lot of money, and it hurts the economy. When severe floods occur you also need to make sure that the threat of disease is controlled. Hurrican Katrina resulted in 135$ billion in property damage. That really hurt the economy that year. When severe weather does damage it can also raise the price of insurance, and this hurts the everyday person.

Cleaning up a disaster area also costs a lot of money. If too many extreme storms hit in a certain time frame the impact on the economy can be disastrous.

5.Drought is an effect of global warming that we are already seeing right now. Many countries are finding that they are currently receiving more storms and rising waters, while other countries are suffering from drought. As the climate of the Earth warms, experts from Scientific American predict that drought conditions could increase by as much as 66 percent. Drought will mean a shrinking water supply and a decrease in crops. Drought can mean a danger for global food production and supply. This also mean that several countries experiencing drought could have a major famine on their hands. Currently, India, Pakistan, and some parts of Africa are already experiencing droughts. It is sad to say but experts are predicting that it will get much worse. One important effect global warming is having on our planet, is that it is producing more intense storms and floods. When you look at the scientific data concerning storms and floods in the last 30 years, you will see that category 4 and 5 hurricanes have nearly doubled in occurence. What many people don't know or realize is that warm waters give hurricanes their strenght and power. Many scientists today are associating the increase in ocean and atmospheric temperatures to the rate of violent storms. Between the years 1905 and 2005 the frequency of hurricanes has been on the rise. From 1905 to 1930 there were an average of 3.5 hurricanes per year, 5.1 between 1931 and 1994, and 8.4 between

1995 and 2005. In 2005 there was a record number of tropical storms that came about, and in 2007 the worst flooding in 60 years hit Britain. More recently, Australia has seen the worst flooding they have had in a long time.

6.Heat waves are also an effect of global warming. It is no secret that temperatures are breaking records in the US and Canada and abroad. More extremely hot summer days are in store for North America and elsewhere if global warming continues unabated. Here are some heat waves facts for you: air pollution in urban areas could get worse with the increased heat. This could result in more people having heart attacts, strokes, and asthma attacks. Children, the elderly, poor, and people of color are more vulnerable to the effects of a heat wave. Scientists have confirmed that the frequency and duration of heat waves has definitely increased by a lot over the last 50 years.

7.One obvious effect of global warming is the shrinking of glaciers, this is happening wherever there are glaciers worldwide. Mountain glaciers have been in retreat for a long time now as global warming continues to effect us. What many people don't realize though is that it is happening more rapidly now then previously believed. Glaciers don't only recede they also shrink vertically. The lakes this melting produces can also lead to more melting. These lakes are like a cancer that is consuming our world's glaciers. Here is a fact that may surprise you: Even if all the world's mountain glaciers were to melt, the effect on sea levels would be small. However, the disappearance of mountain glaciers would have other impacts on nature aside from raising sea levels.

8.Global warming will also bring a rising of sea levels around the world. As glaciers and polar ice sheets melt, the sea levels will rise more and more, and the sea temperatures will also warm. This means more hurricanes, and more flooding due to the rise of the sea level.

The Effects of Global Warming

Nowadays,our worl d is becoming hotter and hotter.And we called it“Global Warming”which is to describe the rise of temperature.The Global Warming has two sides of effect to the world’s creature.First,the Global Warming means there is more carbon dioxide in our atmosphere.So some plants can grow faster and stronger than before.This is its good effect.But on the other hand,the Global Warming will bring us more disasters than fortune.Because of the more and more carbon dioxide in the atmosphere,the earth’s temperature is risin g day by day.The high temperature will cause many serious problems.Like the ice of Antarctica and Arctic Ocean begin to melting.After that happen, the height of sea level will lift.Then some terrible disasters will coming,like tsunami and so on.Maybe some countries,for example like Japan and some coastal cities will be submersed. One reason of Global Warming is that too much industrial emissions and poisonous gases which were made by human beings vented to our atmosphere.Especially methane and carbon dioxide.These gases make the temperature rise day afteer day.And that will cause many natural disasters.Like tsunami,flood, drought and so on. Finally ,if we don’t stop, the world will become a death world without lives.Our fate will like the dinosaurs.Another main reason of Global Warming is the fast growing of

the world’s population.So if we don’t control the speed of growing population,the situation will be worse. So is it already too late to prevent the Global Warming?I think it is still not too late.If we plant more trees,produce less greenhouse gases like methane and carbon dioxide,and to control the growing of population.The situation of Global Warming will be better.And we must to do it first in our daily lives.Go to work by bus or on foot I think,is the best way to prevent the worse situation of Global Warming.

全球气温变暖的主要原因:人类活动对气候变化肯定是有变化和影响的。人类燃烧煤、油、天然气和树木,产生大量二氧化碳和甲烷进入大气层后使地球升温,大气中二氧化碳排放量增加是造成地球气候变暖的根源。

The main reason for global warming: human activities definitely have an impact on climate cha nge. Human burns coal, oil, natural gas which produced a large amount of carbon dioxide and me thane, and it warmed the earth. The cause of global warming is the increased carbon dioxide emi ssions into the atmosphere.

造成的危害:首先是自然生态会发生变化;土地荒漠化,森林退向极地,雨量增加,冬天更湿,夏天更旱,旱涝灾害增加,热带将酷热无比,人类难以生存。其次是两极冰块大面积熔化,使海平面上升,那将使生活在沿海的占世界 1/3的人口无家可归,世界许多港口城市淹没于一片汪洋之中。

Harms: first, to change the natural ecology; land desertification, forest back to the polar region s, increased rainfall in winter, wetter, more droughts in summer, increased droughts and floods, tr opical would be extremely hot, human difficult to survive. Second, the melting polar ice, a large a rea, so that sea level rise, which will live in coastal areas of the world's 1 / 3 of the population ho meless, many of the world port city submerged in a sea of.

人们过去一向认为,多种植树木有助于减缓全球气温升高的现象。不过,科学家如今指出,如果地球气温再升高 2摄氏度,森林反而可能成为二氧化碳的净排放来源。

植物会吸收也会排放二氧化碳;健康的森林,尤其是热带地区的森林所吸收的温室气体,会比它们排放的来得多。不过,如果这些森林受到破坏、生病或是死亡,蓄积在这些森林里的二氧化碳就会被释放出来。

人类砍伐森林时进行的焚烧和摧毁所释放的温室气体,占了总碳排放量的 20% 森林可吸收四分之一的总碳排放量,随着它们日益消失,或是成为净排放来源,空气中的二氧化碳将大幅度增加。”

People used to always think that, more than planting trees help slow global warming phenome non. However, scientists have now pointed out that if global temperatures rise another 2 degrees Celsius, the forest but it may become a net carbon dioxide emission sources.

Plants absorb carbon dioxide emissions will be; the health of forests, especially tropical forests absorb the greenhouse gas emissions than they are to much. However, if these forests are destro yed, illness or death, accumulation of carbon dioxide in these forests will be released.

When human burning of deforestation and destruction of the release of greenhouse gases, of t he total carbon emissions by 20% of the forest can absorb a quarter of the total carbon emissions , as they increasingly disappear, or become a net source of emissions, carbon dioxide in the air wil l increase significantly.

从以上分析可以看出,影响气候变化的因素极其复杂,天体运行和地球运动的威力比人的影响不知要大多少倍,它可以使天气变热,也能让地球变冷。而人的力量在大自然面前显得非常渺小,连一场台风吹来也只有躲避的份儿,大自然的力量是根本抗御不了的。肆无忌惮地糟践自然,人类必然会受到严厉惩罚。人类应该尽一切努力,去做好应该也能够做好的事情。大力发展低碳经济已经成了国际社会的共识。

全球变暖会使我们没有冬天。“四季少了夏和冬”绝对不是好事。全球变暖是指全球气温升高。近100多年来,全球平均气温经历了冷-暖-冷-暖两次波动,总得看为上升趋势。进入八十年代后,全球气温明显上升。1981~1990年全球平均气温比100年前上升了0.48℃。导致全球变暖的主要原因是人类在近一个世纪以来大量使用矿物燃料(如煤、石油等),排放出大量的CO2等多种温室气体。由于这些温室气体对来自太阳辐射的短波具有高度的透过性,而对地球反射出来的长波辐射具有高度的吸收性,也就是常说的温室效应",导致全球气候变暖。全球变暖的后果,会使全球降水量重新分配,冰川和冻土消融,海平面上升等,既危害自然生态系统的平衡,更会威胁到人类的食物供应和居住环境。

Global warming would we have no winter. "Summer and winter seasons less" absolutely not a good thing. Global warming refers to i ncrease in the global climate. Nearly 100 years, global aver age temperature through the cold - warm - cold - warm two fluctuations, there was always seen t o rise. Into the eighties, the global temperature has significantly increased. 1981 to 1990, global a verage temperature increase of more than 100 years ago, 0.48 ℃. The main cause of global warm ing is nearly a century of human heavy use of fossil fuels (such as coal, oil, etc.), large amounts of CO2 emissions and other greenhouse gases.

These greenhouse gases on the short-wave radiation from the sun with a high degree of perme ability, while the long-wave radiation reflected from the Earth are highly absorbent, it is often sai d that the greenhouse effect ", leading to global warming. Global warming the consequences of gl obal precipitation will re-distribution, melting glaciers and permafrost, rising sea levels, endanger ing not only the balance of natural ecosystems, but also a threat to the human food supply and liv

ing environment.

现,很多这类动物搬到了高处,可能是因为全球变暖改变了它们的生活习性。同样被迫改变习性的还有北极生物,如北极熊,因为它们赖以生存的海洋浮冰正在逐渐融化。

三、北极花季

北极冰盖的融化会对低纬度的动植物带来问题,而对北极生物圈来说,它完完全全创造了一个阳光明媚的新环境。以前,北极的植物一年中的大部分时间陷在冰层中,现在,冰层在春天更早的时候就融化了,植物们看起来更渴望生长了。研究发现,在新的土壤中,制造叶绿素的光合作用水平比古老的土壤更高,这表明在近几十年里,北极将迎来花季。

四、拔掉塞子

在刚过去的几十年里,有125个湖泊以令人惊讶的速度从北极消失,这说明全球变暖在地球的两极作用得特别快。在这些失踪湖泊周围的调查显示,湖底的永久冻土可能已经融化。当这种永久冻土融化后,湖里的水就会渗入泥土,把湖泊排干,有学者形象地把这种现象比喻为“拨掉了浴缸中的塞子”。当湖泊消失后,它们所支持的生态系统也就失去了家园。五、大规模的解冻

地球温度的升高不仅融化了巨大的冰川,而且融化了地表以下的永久冻土层。冻土层的解冻会造成土地的高低不平,因此会出现土地下陷而危及地面的建筑,如铁路轨道、高速公路及房屋。如果解冻发生在地势较高的地方,如山区,则很可能引起泥石流等自然灾害。最新研究还发现,一些类似于天花等已灭绝的疾病可能存在于冻土中的古老尸体中,随着冻土层的解冻,它们将再一次复活,回到现代人类中间。

六、适者生存

全球变暖让春天来得更早了,早起的鸟儿未必会有虫子吃了。生物钟的变化会随着基因带入下一代。因为一年中植物开花提早了,所以那些按照正常时间进行迁徙的动物可能会错过它们所有的食物,而那些能调整自己的生物钟早早出发的动物就有了更多的生存机会,然后把基因传给它们的下一代,就这样最终改变了整个种群的基因档案。

七、卫星加速

地球变暖的一大原因----二氧化碳排放增加,使大气层发生了离奇的扭曲。空气在地球大气层的最外层已经十分稀薄,但空气分子仍然会对卫星运动形成阻力,拖慢卫星的运动,因此需要地面人员周期性地加快卫星运行速度以使它回到正确的轨道上。但现在,那里的二氧化碳浓度在增加。当较低层大气中的二氧化碳分子相互碰撞而产生热量时,那里的大气温度会上升,相反,较高层大气中因为分子碰撞少,热量会向下传递,造成较高层大气的温度下降。在高层大气中,二氧化碳上升得越多,温度下降发生得越多,从而形成空气下沉,大气密度增大,将卫星“拖”得更慢。

八、山脉反弹

虽然登山运动员不会注意到山脉的增高,但实际上,阿尔卑斯山脉以及其它山脉在过去的

一个世纪中已经增高不少,原因在于山顶冰川的融化。几千年来,这些冰川的重量压在地球表面,是向下的极大的压力。随着冰川的融化,重量减轻,地表正在逐步反弹。因为全球变暖加速了冰川的融化速度,所以山脉反弹的速度也在加快。

九、遗迹被毁

世界上有很多古老遗迹,就象人类文明的博物馆,抵挡了岁月的考验,记录了人类的过去。但全球变暖的影响可能最后会把它们毁掉。上升的海平面和更多极端气候将危及这类不可再生的瑰宝。因气候变暖而引起的洪水已经摧毁了一座600年前的遗迹----苏可泰城,泰国曾经的首都。

十、森林大火

当变暖的气候融化了大量冰川并制造了更多猛烈飓风的同时,它也在美国点燃了一次次的森林大火。在刚过去的几十年里,美国西部的森林大火比以往更多,持续时间也更长。科学家们将猖獗的大火跟气温上升联系起来。因为春天来得更早了,融雪期也随之提早,山林地区更为干燥并且干燥时间更久,于是增加了起火的机会。

Perhaps you have heard of global warming over the next produces a series of consequences: ri sing temperatures, melting ice caps, rising sea levels, but in fact, climate change is a number of al ternative ways to demonstrate in front of us. Think about that raging fire, that 25-meter-long iceb erg, that the lake disappeared, and the unusual number of old diseases, allergies, and the resurre ction of it.

First, increased allergies

Do you find torture every spring sneezing and itchy eyes your even more serious in recent year s? If so, you can partly be blamed on global warming. Over the past ten years, more and more Am ericans suffer from seasonal allergies and asthma. Although fundamentally, lifestyle changes and i ncreased pollution make people more susceptible to respiratory disease, but the study found that with global warming-related carbon dioxide concentration and temperature increasing to promot e early flowering plants, and produce more pollen. More allergens occurs much earlier, allergy se ason will last much longer ---- So, prepare your tissues instead.

Second, go mountain climbing

From the early twentieth century, we must climb higher to see where our favorite chipmunk an d a squirrel. Study found that many of these animals moved to higher places, probably because of global warming have changed their habits. There are also forced to change the habits of Arctic cr eatures, such as polar bears, because they are the survival of marine ice is melted.

3, Arctic bloom

Arctic ice cap melting will cause problems in low latitudes, plants and animals, while the Arctic biosphere, it created a completely new environment sunny. Previously, Arctic plant of the year in most of the time stuck in the ice, and now, the ice earlier in the spring when melting, plants have

seemed more eager to grow. Study found that, in the new soil, the level of manufacture of chloro phyll photosynthesis higher than the old soil, which indicates that in recent decades, the Arctic wi ll usher in the flowering season.

4, unplug the plug

In just the past few decades, there are 125 lakes with surprising speed away from the North Pol e, indicating that the global warming effect on Earth's poles much faster. Missing around these lak es survey the lake bottom may have been melting permafrost. When this melting permafrost, the lake's water will infiltrate into soil, the lakes drained, some scholars described such phenomenon as an analogy for the "pulled off a bathtub plug." When the lakes disappear, the ecosystems they support also lose their homes.

Five large-scale thawing

Earth's temperature is not only a huge glacier melting, and melting of the permafrost below th e surface. Thawing permafrost will cause uneven land, it will jeopardize the soil subsidence groun d construction, such as railway tracks, highways and housing. If thawing in higher ground, such as mountains, it is very likely to cause landslides and other natural disasters. New research also foun d that some similar to smallpox and other diseases that may be extinct there in the frozen soil in t he old body, with the thawing of permafrost, which will once again be revived, returned to the mi ddle of modern humans.

6, survival of the fittest

Let spring come earlier, global warming, and early bird gets the worm may not be eaten. Varies with the biological clock gene into the next generation. Because flowering plants year earlier, so t hat the normal time for migratory animals may miss all of their food, and those who can adjust th eir biological clocks of animals, starting early will have a greater chance of survival, then the gene transfer to their next generation, it will ultimately change the entire population of the gene file. 7, satellite acceleration

A major cause of global warming carbon dioxide emissions increase ---- so bizarre twist occurre d in the atmosphere. Air in the outermost layer of the Earth's atmosphere is already very thin, bu t air molecules still form a resistance movement would be satellite, slow down the movement of satellites, ground staff needed to run periodically to speed up satellite speed to make it back on t he right track. But now, where the carbon dioxide concentration is increasing. When the lower lay er of the atmosphere of carbon dioxide molecules collide with each other and generate heat whe n, where atmospheric temperature will rise, on the contrary, a higher level of molecular collisions in the atmosphere because less heat will be passed on down the

Than the upper atmosphere caused by temperature drop. In the upper atmosphere, the more carbon dioxide rose, the more the temperature drop occurs, thus forming the air sinks, atmosphe ric density, the satellite "delay" more slowly.

8, mountains rebound

Although the mountain climbers will not notice the increase, but in fact, the Alps and other mo untain ranges in the past century has increased a lot because of melting glaciers Peak. For thousa nds of years, these glaciers weight at the Earth's surface, is a great downward pressure. As glacier s melt, weight, surface is gradually rebounding. Because global warming has accelerated the rate of melting glaciers, it is also accelerating the speed of rebound mountains.

9, remains destroyed

There are many ancient monuments in the world, as the museum of human civilization, to with

stand the test of years of recorded human past. However, the impact of global warming may be t he last will destroy them. Rising sea levels and more extreme weather will threaten the treasure of such non-renewable. Due to flooding caused by global warming has destroyed the remains of a 600 years ago, the Soviet Union to Thailand ---- City, the capital of Thailand was.

10, forest fires

When the warming climate melted a large number of glaciers and creating more intense hurric anes, it was in a meeting of the U.S. lit forest fires. In just the past few decades, forest fires in the western United States more than ever, for longer. Scientists will be rampant fires linked with war ming. Because the spring has come earlier, and also followed earlier snowmelt period, forest

防止全球变暖的举手之劳

关掉不必要的电灯难道不是举手之劳吗?事实上我们往往忘记了这一点。白天少开或关掉电灯,夜晚家里人尽量在同一个房间里活动,进出家门时随手关灯……想加入“低碳生活”一族么,不妨看看以下建议。

●及时关电脑

统计数据显示,家庭中75%的用电都耗在使电视、电脑和音响等保持待机状态上。平均一台台式电脑每天耗电60至250瓦。如果一台电脑每天使用4小时,其他时间关闭,那么每年能节省约500元人民币,且能减少83%的二氧化碳排放量。

●多乘公交车

交通产生的二氧化碳占温室气体排放量30%以上,减少此类排放量的最好办法之一是:乘坐公交车。美国公共交通联合会称,公共交通每年节省近53亿升天然气,这意味着能减少150万吨二氧化碳排放量。

●种一棵树

谈到全球变暖,如果你不了解复杂的碳捕捉(CCS)技术,那也不必慌张。事实上“捕捉”二氧化碳的能手就是树木本身。要是你嫌自己种树太麻烦的话,至少可以捐钱给环保组织,让他们代劳。

●选择小房子

人们都向往大房子,但大房子在无形中会增加碳的排放量,还需要更多的能量来加热和制冷,就拿暖气供应来说,大房子需要消耗大量的能源来维持温度。房子越大,对环境的影响也大,现在美国每户家庭每年平均要排放18吨温室气体,要消耗大量的燃料和非再生能源。

●打开一扇窗

我们每年人均排放约25吨二氧化碳,怎样减少这个数字?有一些简单有效的方法:打开一扇窗户,取代室内空调;夏天使用空调时,温度稍微调高几度。数据统计表明,只要所有人把空调调高一度,全国每年能省下33亿度电。

Little effort to prevent global warming: We promote low-carbon lives Lifting a finger to preven t global warming

Turn off unnecessary lights Is not lifting a finger you? In fact, we often forget this. Less open or turn off the lights during the day, night, as family activities in the same room, turning off lights wh en out of the house ... ... would like to join the "low-carbon life" What a family, take a look at the f ollowing recommendations.

● time off the computer

Statistics show that 75% of households have electricity consumed in making television, comput ers and audio, etc. remain on standby status. The average daily consumption of a desktop comput er from 60 to 250 watts. If you use a computer 4 hours a day, other time off, then the annual savi ngs of about 500 yuan, and can reduce carbon dioxide emissions by 83%.

● more by bus

Transport of carbon dioxide greenhouse gas emissions account for more than 30% reduction of such emissions is one of the best ways: By bus. American Public Transportation Association, said public transportation to save nearly 5.3 billion liters per year of natural gas, which means to reduc

e 1.5 million tons o

f carbon dioxide emissions.

● plant a tree

On global warming, if you do not understand the complex carbon capture (CCS) technology, wh ich need not panic. In fact, "capturing" carbon dioxide is the trees themselves experts. If you susp ect your trees too much trouble, at least donate money to environmental organizations, let them do it.

● Select a small house

People are yearning for a big house, but the house will increase in virtually carbon emissions, b ut also require more energy to heat and cooling, taking the heating supply, the big houses consu me a lot of energy to maintain temperature. Bigger house, a large impact on the environment, an d now the United States each year per household on average, 18 tons of greenhouse gas emission s, to consume a large amount of fuel and non-renewable energy sources.

● Open a window

Every year about 25 tons of carbon dioxide emissions per capita, and how to reduce this figure ?

全球气候变化对发展中国家的影响

柴达木盆地气候正由暖干化向暖湿化转型。 柴达木盆地地处青藏高原北部,其主体位于青海省海西蒙古族藏族自治州境内,为阿尔金山、祁连山、昆仑山所环绕,总面积25万多平方公里,是中国四大盆地之一,境内蕴藏着各类丰富的矿产资源,被誉为中国的“聚宝盆”。但这个“聚宝盆”长期被水资源短缺所困扰,生态和经济发展均受制约。 最新气象研究表明,中国西部“聚宝盆”柴达木盆地气候正在由暖干化向暖湿化转型。2009年,盆地内的地下水量新增了2亿多立方米,相当于16个杭州西湖的水量。青海省气候监测评估中心近日发布的《柴达木盆地候变化评估报告》中称,柴达木盆地是青藏高原乃至全国受全球气候变暖影响最为显著的地方,最明显的表现就是升温和降水量的持续增加。 在气温升高的同时,柴达木盆地降水量也在持续增多。据青海省气候中心高级工程师戴升介绍,柴达木盆地大部分地区从1998年以来降水量持续增加,增加趋势明显大于青海省其他地区。卫星遥感表明,近年来柴达木盆地湖泊面积不断增大、水位明显上升,其中2008年哈拉湖面积比2005年增大7.38平方公里。 气象专家预测,未来10年至20年,柴达木盆地的气温将继续上升,可能比20世纪90年代平均值偏高左右;降水还将继续增加,与20世纪90年代的平均值相比将偏多5%-19%左右;柴达木等河流的径流量比20世纪90年代的平均值将偏多10%左右。中国“聚宝盆”气候暖湿化的趋势还将在未来表现得更为明显。 气候变化规则将重塑全球产业结构 第一,能源消费成本的提高将在一定程度上改变不同生产要素之间的构成,进而影响全球产业的布局。不同产业的碳密度、不同国家同一产业的碳密度差异很大。比如,能源业的碳密度大约是服务业的10倍,发展中国家的碳密度大约是发达国家的4倍以上。因此,减排所引发的能源成本提高,对不同产业和不同国家的压力差异是非常明显的。 第二,化石能源与清洁能源的消费成本比价变化有可能会改变全球能源供求的格局。气候变化规则虽不能改变清洁能源与化石能源的生产成本比价,但可以改变两者间的消费成本比价。一旦确立全球气候变化规则,清洁能源的发展将不再受制于化石能源的价格波动,因为每个国家(企业)都将面临减排额度的制约。这样,化石能源的现行供求格局将不可避免地受到冲击。 第三,围绕减排所开展的技术创新将成为产业技术进步的方向之一。国际气候变化规则既为减排技术创新提供动力,也将不可避免带来压力。未来产业发展的空间越来越取决于碳密度的高低,企业盈利的空间也将越来越取决于减排的能力大小,因而产业技术进步与碳密度会有越来越高的关联度。很多产品的性能和功效没有发生本质的改变,但由于其

引起全球变暖的原因及处理方法

引起全球变暖的原因及对策 全球气候变暖是一种“自然现象”。由于人们焚烧化石矿物以生成能量或砍伐森林并将其焚烧时产生的二氧化碳等多种温室气体,由于这些温室气体对来自太阳辐射的可见光具有高度的透过性,而对地球反射出来的长波辐射具有高度的吸收性,也就是常说的“温室效应”,导致全球气候变暖。近100多年来,全球平均气温经历了冷-暖-冷-暖两次波动,总的看为上升趋势。进入八十年代后,全球气温明显上升。全球变暖的后果,会使全球降水量重新分配,冰川和冻土消融,海平面上升等,既危害自然生态系统的平衡,更威胁人类的食物供应和居住环境。 一、引起全球变暖的因素 (一)人为因素 1.人口剧增因素。近年来人口的剧增是导致全球变暖的主要因素之一。同时,这也严重地威胁着自然生态环境间的平衡。这样多的人口,每年仅自身排放的二氧化碳就将是一惊人的数字,其结果就将直接导制大气中二氧化碳的含量不断地增加,这样形成的二氧化碳“温室效应”将直接影响着地球表面气候变化。 2.大气环境污染因素。目前,环境污染的日趋严重已构成一全球性重大问题,同时也是导致全球变暖的主要因素之一。现在,关于全球气候变化的研究已经明确指出了自上个世纪末起地球表面的温度就已经开始上升。 3.海洋生态环境恶化因素。目前,海平面的变化是呈不断地上升趋势,根据有关专家的预测到下个世纪中叶,海平面可能升高50cm。如不采取及对措施,将直接导致淡水资源的破坏和污染等不良后果。另外,陆地活动场所产生的大量有毒性化学废料和固体废物等不断地排入海洋;发生在海水中的重大泄(漏)油事件等以及由人类活动而引发的沿海地区生态环境的破坏等都是导致海水生态环境遭破坏的主要因素。 4.土地遭侵蚀、盐碱化、沙化等破坏因素。造成土壤侵蚀和沙漠化的主要原

最新版地理七年级上册备课素材全球气候变暖的危害

全球气候变暖得危害 全球气候变暖是一种自然现象。由于人们焚烧化石燃料,如石油,煤炭等,或砍伐森林并将其焚烧时会产生大量得二氧化碳等温室气体,这些温室气体对来自太阳辐射得可见光具有高度透过性,而对地球发射出来得长波辐射具有高度吸收性,能强烈吸收地面辐射中得红外线,导致地球温度上升,即温室效应。而当温室效应不断积累,导致地气系统吸收与发射得能量不平衡,能量不断在地气系统累积,从而导致温度上升,造成全球气候变暖这一现象。全球变暖会使全球降水量重新分配、冰川和冻土消融、海平面上升等,不但危害自然生态系统得平衡,而且威胁人类得生存。 1. 生态 首先,全球气候变暖导致海平面上升,降水重新分布,改变了当前得世界气候格局;其次,全球气候变暖影响和破坏了生物链、食物链,带来更为严重得自然恶果。例如,有一种候鸟,每年从澳大利亚飞到我国东北过夏天,但由于全球气候变暖使我国东北气温升高,夏天延长,这种鸟离开东北得时间相应变暖,再次回到东北得时间也相应延后。结果导致这种候鸟所吃得一种害虫泛滥成灾,毁坏了大片森林。另外,有关环境得极端事件增加,比如干旱、洪水等。 2. 政治 限制二氧化碳得排放量就等于是限制了对能源得消耗,必将对世界各国产生制约性得影响。应在发展中国家“减排”,还是在发达

国家“减排”成为各国讨论得焦点问题。发展中国家得温室气体排放量不断增加,2013年后得“减排”问题必然会集中在发展中国家。有关阻止全球气候变暖得科学问题必然引发“南北关系”问题,从而使气候问题成为一个国际性政治问题。 3. 气候 全球气候变暖使大陆地区,尤其是中高纬度地区降水增加,非洲等一些地区降水减少。有些地区极端天气气候事件(厄尔尼诺、干旱、洪涝、雷暴、冰雹、风暴、高温天气和沙尘暴等)出现得频率与强度增加。 4. 海洋 随着全球气温得上升,海洋中蒸发得水蒸气量大幅度提高,加剧了变暖现象。而海洋总体热容量得减小又可抑制全球气候变暖。另外,由于海洋向大气层中释放了过量得二氧化碳,因而真正得罪魁祸首是海洋中得浮游生物群落。 5. 农作物 全球气候变暖对农作物生长得影响有利有弊。其一,全球气温变化直接影响全球得水循环,使某些地区出现旱灾或洪灾,导致农作物减产,且温度过高也不利于种子生长。其二,降水量增加尤其在干旱地区会积极促进农作物生长。全球气候变暖伴随得二氧化碳含量升高也会促进农作物得光合作用,从而提高产量。

全球化的影响 范文(一) Nowadays we can enjoy the same films, fashions, brands, advertisements and TV channels. The evident difference between countries is disappearing. To what extent do you think the disadvantages overweight the advantages of this? Globalization creates conditions for widening international exchanges, strengthening mutual understanding between nations, expanding cultural, educational, and scientific cooperation between nations and countries, enjoying the cultural achievements of people around the world which encourages the process of modernization and the enrichment of national culture. However, these conditions also create the possible danger of diminishing the national culture with a negative impact on the pre123vation of national identity. Through globalization and an open door policy, erroneous concepts and a lowering of ethical standards, a selfish and individualistic lifestyle and harmful cultural products can easily be imported into the country. At present, modern information technology which in the main is controlled by US is hourly and intensively disseminating US ideology, way of life, culture and films across the world. Even US food is promoted so that some people consider globalization as global Americanization. During the process of economic globalization, inequality between developed and developing countries has been increasing and the gap between the rich and the poor has become wider, most of the result of globalization go to assist developed countries. Globalization does not pose equal interests and risks to all nations. With an overwhelming advantage compared to most of the developing countries in terms of finance and the level of science and technology, developed ca123alist countries control the situation of economic globalization. For these reasons, globalization is a fierce and complicated struggle in both cultural and ideological fields. We take the initiative in international economic integration but also have to take the initiative in fighting to keep our distinct culture resisting pro-foreign and cross-bred phenomena, and overcoming the psychology of preferring money over ethical values.

全球气候变暖的原因与对策

全球气候变暖的原因与对策 全球气候变暖问题日趋严峻,由此导致的各类问题正在严重地威胁着人类赖以生存的环境。气候变暖已成为不可回避的重大理论和实际问题。气候变暖的明显化,让各种危害逐步进入人们的日常生活,因此气候变化已经不仅仅是一个学科问题而日渐成为人们共同关心的重大社会问题。气候变暖引发的问题也从单一性向多样化转变,从已知向未知发展。它引发的各种新现象改变着人类的生存状态。最主要是它所引发的灾害以不同形式出现,让人们不能预知,同时它又是全球范围的,这使得气候变暖成为了全世界所共同关注的问题。 全球气候变暖的原因有一下几点: 一是人口剧增因素:近年来人口的剧增是导致全球变暖的主要因素之一。同时,这也严重地威胁着自然生态环境间的平衡。这样多的人口,每年仅自身排放的二氧化碳就将是一惊人的数字,其结果就将直接导致大气中二氧化碳的含量不断地增加,这样形成的二氧化碳“温室效应”将直接影响着地球表面气候变化。 二是大气环境污染因素:目前,环境污染的日趋严重已构成一个全球性重大问题,同时也是导致全球变暖的主要因素之一。现在,关于全球气候变化的研究已经明确指出了自上个世纪末起地球表面的温度就已经开始上升。 三是海洋生态环境恶化因素:目前,海平面的变化是呈不断地上升趋势,根据有关专家的预测到下个世纪中叶,海平面可能升高50cm。陆地活动场所所产生的大量有毒性化学废料和固体废料等不断地排入海洋,发生在海水中的重大泄油事件以及由人类活动而引发的沿海地区生态环境的破坏等都是导致海水生态环境遭破坏的主要因素。 四是森林资源锐减因素:在世界范围内,由于受自然或人为的因素而造成森林面积正在大幅度地锐减。 五是地球周期性公转轨迹的变动:地球周期性公转轨迹由椭圆形变为圆形轨迹距离太阳更近。根据某科学家的研究地球温度曾经出现过高温和低温的交替,是有一定的规律性的。 碳循环是地球上最主要的生态地化循环,它支配着大部分陆地生态系统的物质循环,深刻影响着人类赖以生存的生物圈。全球气候变化与碳循环动态及其反馈效应密切相关。碳循环失衡,改变了地球生物圈的能量转换形式。因此,针对全球气候变暖的影响因素我们有以下措施: 一是保护森林的对策方案:今日以热带雨林为生的全球森林,正在遭到人为持续不断的

全球气候变暖的原因、影响、措施

全球气候变暖的原因、影响、措施近100多年来,全球平均气温经历了冷-暖-冷-暖两次波动,总得看为上升趋势。1998年和2005年是近一千年来温度最高的两年。近百年来全球平均地表温度上升了0.74℃,其中尤以1910~1945年和1979~2005年的升温最为明显。20世纪后半叶北半球平均温度很可能比近500年中任何一个50年时段的平均温度都高,并且可能至少在最近1300年中是最高的。 全球气候变暖的原因有两方面: 1、大气层遭到破坏,严重的污染以及温室效应。 大气层和地表这一系统就如同一个巨大的“玻璃温室”,使地表始终维持着一定的温度,产生了适于人类和其他生物生存的环境。在这一系统中,大气既能让太阳辐射透过而达到地面,同时又能阻止地面辐射的散失,我们把大气对地面的这种保护作用称为大气的温室效应。造成温室效应的气体称为“温室气体”,它们可以让太阳短波辐射自由通过,同时又能吸收地表发出的长波辐射。这些气体有二氧化碳、甲烷、氯氟化碳、臭氧、氮的氧化物和水蒸气等,其中最主要的是二氧化碳。近百年来全球的气候正在逐渐变暖,与之同时,大气中的温室气体的含量也在急剧地增加。许多科学家都认为,温室气体的大量排放所造成温室效应的加剧可能是全球变暖的基本原因。 排放温室气体的人类活动包括:所有的化石能源燃烧活动排放二氧化碳。在化石能源中,煤含碳量最高,石油次之,天然气较低;化石能源开采过程中的煤炭瓦斯、天然气泄漏排放二氧化碳和甲烷;水泥、石灰、化工等工业生产过程排放二氧化碳;水稻田、牛羊等反刍动物消化过程排放甲烷;土地利用变化减少对二氧化碳的吸收;废弃物排放甲烷和氧化亚氮。人类燃烧煤、油、天然气和树木,产生大量二氧化碳和甲烷进入大气层后使地球升温,使碳循环失衡,改变了地球生物圈的能量转换形式。自工业革命以来,大气中二氧化碳含量增加了25%,远远超过科学家可能勘测出来的过去16万年的全部历史纪录,而且目前尚无减缓的迹象。 2、人口膨胀,超载超量,过度开垦,乱砍滥伐,滥采地下水有关。 近年来人口的剧增是导致全球变暖的主要因素之一。同时,这也严重地威

Globalization With the rapid social and economic development, globalization comes not to be an unfamiliar word to all of us. Though we are living in the affection of it, yet it is hard to tell it’s advantages and disadvantages. Globalization phenomenon is an outcome of social development. The typical types are economic globalization, cultural globalization. As we all know, it is a double-edged sword. Therefore, we must pay more attention on this phenomenon and it’s development trend. Globalization has so many advantages, such as it makes the world become a small village and let people touch each other more convenient and easy, it increase free trade between nations and give the developing countries a terrific opportunity to develop themselves in all aspects quickly. What’s more, it can reduce the cultural barriers and let various of cultural get a better communication and development. On the contrary, it also has a lot of disadvantages. Because under globalization, every country’s economy can make a great influence of others, it make the economy of the world more fragile. In order to possess the good chance and precious resources, the disputes and even wars may take place between nations. In recent years, great risk of diseases being transported between nations has also become a threaten to people. As the globalization has become an irrevocable trend, we must adjust it. This phenomenon is an opportunity as well as a challenge. Consequently, every person, every

全球化与国际贸易(附带英文)

全球化与国际贸易 由于全球化的原因,国际间的贸易不断增强。 而一些不同国家的传统习惯,也慢慢进入到了贸易里。而一些大家公认的经济的常识也慢慢地被人们所用。 例如 The term globalization, is a concept, but also a process of the development of human society phenomenon. Globalization has many definitions. In the usual sense of globalization refers to the growing global links. The rise of the development of human life based on a global scale and the global consciousness will improve. Between country and country in the political, economic and trade interdependence, globalization also can be explained by the compression and the earth as a whole world. International trade is the exchange activities between different countries of goods and services. International trade is the international transfer of goods and services. International trade also called world trade. International trade is composed of two parts the import and export trade It is sometimes called as the import and export trade. 11111促进国家间特别是大国间的协调与合作 随着经济全球化的深入发展,一个统一的全球经济系统正在逐步形成。各国之间、地区之间的经济利益错综交织,你中有我、我中有你,相互依赖程度不断加深。同时各国对世界市场的争夺也日趋激烈,争端和摩擦接连不断,一波未平,一波又起。而传统经济体制下的零和、输赢规则已为经济全球化环境下的非零和及双输、双赢规则取代,要么一损俱损。因此,任何一个国家,无论其经济实力多么强大,都不能我行我素。各国,尤其是各大国,在处理相互关系和国际关系时客观要求相互沟通。协调与合作正在成为大国关系的主旋律。 近年来,中美关系的改善和发展,就与经济全球化这一因素密不可分。中国是最大的发展中国家,美国是最大的发达国家。冷战结束之后两国关系麻烦不断,一度曾面临严重危机。但是,由于两国经济上的互补性很强,中国拥有广大的市场和发展潜力,美国大量的资金和技术急需开拓国外市场,因而,中美间的经贸关系仍迅速发展。美国是中国的第二大贸易伙伴,中国是美国的第四大贸易伙伴。对中国的直接出口为美国提供了30多万个就业岗位,双边贸易至少为美国工业和服务业提供了上百万个工作岗位。经济上的互惠互利推动着两国间的接触、对话不断发展,双方搁置分歧,增进了解,加强协调,扩大合作。两国建立了面向21世纪的建设性战略伙伴关系。两国元首频繁互访,并设立首脑热线,及时就全球问题交换看法和意见。中美两国还在资源、能源、环保、安全等全球性问题上进一步加强合作。Promote inter country especially the coordination and cooperation among the great powers

固碳速率,导致植物生长的增候变化的研究已经明确指出了自上个加,即二氧化碳的增产效应,这是全世纪末起地球表面的温度就已经开始球变暖的正面影响。但是与正面影响上升。 相比,全球变暖对人类活动的负面影(3)海洋生态环境恶化因素:目响将更为巨大和深远。今年8月份前,海平面的变化是呈不断地上升趋CCTV报道,由于气候变暖的影响,势,根据有关专家的预测到下个世纪珠穆朗玛峰的顶峰下降了米。祁中叶,海平面可能升高50cm。如不采连山冰川缩减危及河西走廊:近年来,取及对措施,将直接导致淡水资源的祁连山冰川融化比上个世纪70年代减破坏和污染等不良后果。另外,陆地少了大约10亿立方米,冰川局部地区活动场所产生的大量有毒性化学废料的雪线正以年均米的速度上升。和固体废物等不断地排入海洋;发生专家分析,冰川退缩,雪线上升除自在海水中的重大泄(漏)油事件等以及然气候因素外,另一个主要原因是人由人类活动而引发的沿海地区生态环口膨胀,超载超牧,过度开垦,乱砍境的破坏等都是导致海水生态环境遭 破坏的主要因素。 滥伐,滥采地下水有关。 (4)土地遭侵蚀、沙化等破坏因 素。造成土壤侵蚀和沙漠化的主要原因是不适当的农业
